INTRODUCTION TO OIL SEALS AND HOW THEY ARE USED
When the oil seal material and the chemical are not compatible, there will be a chemical attack, which increases at high temperatures. The only way to remedy this is to select the right material for your application. If you’ll be dealing with harsh chemicals, choose oil seals that are made with reliable materials for their compatibility.
- In the realm of marine engines, the significance of spark plug wires cannot be overstated. These critical components serve as the conduits through which electrical energy is transmitted from the ignition system to the spark plugs, igniting the air-fuel mixture and propelling the boat forward. The importance of high-quality marine spark plug wires is underscored by their direct impact on engine performance, fuel efficiency, and overall reliability.

- Replacing the front valve cover gasket is an important maintenance task that should not be neglected. If you notice oil leaking from the front valve cover or if you smell burning oil, it may be a sign that the gasket needs to be replaced. Ignoring the issue can result in low oil levels, engine overheating, and even engine failure.
However, the new variant also comes with less good properties. Namely less flexibility and less resistance during assembly. Most damages therefore occur during the installation of PTFE oil seals.
- a. Nitrile Rubber (NBR) – this is the most commonly used material. It has good heat resistance properties and has good resistance to salt solutions, oils, hydraulic oils, and gasoline. Operating temperatures are recommended from -40 to 248⁰ F (-40 to 120 deg.C). Nitrile also functions well in a dry environment, but only for intermittent periods. The disadvantage of this material is poor chemical resistance.
A final step in preparation for assembly is to lubricate the shaft, sealing lip and bore with sufficient oil. This will allow the oil seal to slide more easily over the shaft and prevent dry running after the first rotation. Always use oil or grease that is compatible with the oil seal material. In addition, when sliding over the shaft, the oil seal comes into contact with the keyway, threads and grooves. By taping or covering the shaft at the location of these irregularities with oil-soaked paper, the oil seal can be mounted without damage to the sealing lip.
- The Importance of Proper Valve Cover Gasket Replacement
The basic principle of an oil seal is fairly straightforward. It is installed adjacent to the bearing, with the flexible lip against the rotating shaft and the casing pressed into the housing to hold the seal in place. It’s important that the sealing lip is lubricated to prevent it from overheating as a result of any generated friction. It’s also crucial to understand which type of seal is appropriate for your particular machinery. Before selecting your seal, consider the environment, temperature, pressure and shaft speed of your machine, as well as the type of medium the seal will come into contact with during operation. These considerations will all determine the size, colour, and type of lip material or sealing element to choose, and whether it can be sealed in or sealed out.
